摘要
氯化原位接枝过程是一种基于自由基反应的改性聚合物新方法,经该方法改性的聚合物性能显著改变,充分展现了弱影响、强响应的特征。本文简述了氯化原位接枝反应过程、机理,剖析了氯化原位接枝产物的结构特征,并对各类接枝共聚产物结构与性能关系进行了归纳和总结。详细介绍了各类接枝产物的不同用途,例如用于热塑性弹性体、木板粘合剂、增韧改性剂、成膜涂料等。最后对氯化原位接枝过程更广泛的应用及今后的发展趋势进行了展望。
In-situ chlorinating graft copolymerization is a new method of modified polymer based on free radical reaction. The properties of polymer modified by this method are improved obviously,and the characteristics of weak influence and strong response are shown. In this paper,the process and mechanism of in-situ chlorinating graft reaction are briefly introduced,and the structural characteristics of in-situ graft products are analyzed,also the relationship between the structure and performance of the graft copolymers is summarized. The different uses of various grafting products,such as thermoplastic elastomers,wood adhesive,toughening modifier,film coating and so on are introduced in detail. The application and future development trend of in-situ chlorinating grafting are prospected.
